How to set up git to use the GPG Suite

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

  1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
  2. Create or import a key -- see below for https://keybase.io
  3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
  4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Quant Cup 1's winning order book implementation
/*****************************************************************************
* QuantCup 1: Price-Time Matching Engine
*
* Submitted by: voyager
*
* Design Overview:
* In this implementation, the limit order book is represented using
* a flat linear array (pricePoints), indexed by the numeric price value.
* Each entry in this array corresponds to a specific price point and holds
* an instance of struct pricePoint. This data structure maintains a list

This is a script to convert every table in a Microsoft SQL Server database backup (.bak file) to a .csv file
#!/usr/bin/env bash
# import an MS SQL .bak backup file to an MS SQL database, then export all
# tables to csv. run this script as `import.sh <filename>`. It expects to be
# run in the same directory as the backup file.
# this is only tested on my mac (OS X Catalina). I tried to stick to posix, but
# It will probably require some tweaking for you. I hope it gives a general
# sense of what you need to do at the very least.
